[Windows Phone 8] StartCoroutine incompatible?

Hi there, I've been dealing with an animation bug all afternoon and it's leading me to believe it's an issue with Unity and Windows Phone.

Device: Lumia 520

So I have this code that plays an animation before an object gets destroyed. It works as intended with mouse input running through the editor. However on the phone it doesn't play the animation.

void Update()
{
CheckForTouch();
}


private bool trigger = false;

private IEnumerator PlayAnimation()
{
animController.SetBool("Dead", true);

yield return new WaitForSeconds(0.4f);

TakeDamage(this.Health);
animController.SetBool("Dead", false);
}

private void CheckForTouch()
{
foreach (Touch item in Input.touches)
{
Vector3 touchPosition = Camera.main.ScreenToWorldPoint(item.position);

if (collider2D == Physics2D.OverlapPoint(touchPosition))
{
StartCoroutine(PlayAnimation());
}

}

//Mouse code
Vector3 touchPositionKeyboard = Camera.main.ScreenToWorldPoint(Input.mousePosition);
if (collider2D == Physics2D.OverlapPoint(touchPositionKeyboard))
{
StartCoroutine(PlayAnimation());
}
}

Is this an issue with Windows Phone compatibility?

 

Note that animController.SetBool("Dead",true); triggers the animation, likewise setting it to false sets it back to idle.
